To be clear for anyone who isn’t familiar, the ~28 days vs ~30 days thing comes from the number of days it takes to complete an orbit vs the number of days it takes for the sun to be in the same relative position, respectively. Historically, calendars have followed the latter because that’s what dictates what phase the moon is in. The discrepancy happens because the earth is orbiting the sun at the same time the moon is orbiting the earth.

Rules:

  1. All posts must be memes and follow a general meme setup.

  2. No unedited webcomics.

  3. Someone saying something funny or cringe on twitter/tumblr/reddit/etc. is not a meme. Post that stuff in !the_dunk_tank@www.hexbear.net, it's a great comm.

  4. Va*sh posting is haram and will be removed.

  5. Follow the code of conduct.

  6. Tag OC at the end of your title and we'll probably pin it for a while if we see it.

  7. Recent reposts might be removed.

  8. Tagging OC with the hexbear watermark is praxis.

  9. No anti-natalism memes. See: Eco-fascism Primer
